# The Ingredients You'll Need:
→ Pastry
01 - 2 cups all-purpose flour
02 - 1/2 cup cold unsalted butter, cubed
03 - 1 egg yolk
04 - 2 to 3 tablespoons cold water
05 - 1/2 teaspoon salt
→ Filling
06 - 1 medium sweet potato, peeled and diced
07 - 1 small butternut squash, peeled and diced
08 - 2 tablespoons olive oil
09 - 1 large red onion, thinly sliced
10 - 2 tablespoons unsalted butter
11 - 2 tablespoons pure maple syrup

14 - 2/3 cup crème fraîche

# Step-by-Step Instructions:
01 - Heat the oven to 400°F.
02 - Combine flour and salt in a large bowl. Incorporate cold butter until mixture resembles coarse crumbs. Mix in egg yolk and add cold water gradually until dough forms. Shape into a disk, wrap with plastic film, and chill for 20 minutes.
03 - Toss sweet potato and butternut squash with olive oil, salt, and pepper. Spread on a baking sheet and roast for 20 to 25 minutes, until golden and tender. Reduce oven temperature to 350°F.
04 - Melt butter in a skillet over medium heat. Sauté red onion until soft and caramelized, about 10 to 12 minutes. Add maple syrup and cook an additional 2 minutes. Remove from heat.
05 - Roll out chilled pastry on lightly floured surface. Line a 9-inch tart pan, prick base with fork. Blind-bake for 10 minutes.
06 - Whisk together eggs, crème fraîche, thyme, salt, and pepper in a bowl.
07 - Layer roasted vegetables and caramelized onions into tart shell. Sprinkle crumbled goat cheese evenly. Pour egg custard over filling.
08 - Bake at 350°F for 25 to 30 minutes until filling is set and lightly golden.
09 - Allow tart to cool slightly before unmolding. Optionally, decorate with baked pastry cutouts shaped like maple leaves.
